Referring more specifically to the drawings, and first with reference to Figures 1 to 7, the beverage making and dispensing apparatus as disclosed therein is designated generally 22 and includes a supporting structure shown as comprising a cabinet 23 having a hinged front wall 24 supported for swinging movement about a vertical axis on the hinges 25 and which is normally retained ina closed position by a conventional latchstructure 26..

As best seen in Figures 2 and 4, a storage tank 27 is supported adjacentthe top of a rear wall 28 of thecabi net. A water supply pipe 29, leading from any suitable source of water supply under pressure,.preferably extends into the tank through the rear wall 28; A conventional float actuated valve 30 is connected to the outlet end of the conduit 29 for regulating the discharge ofwater there: from into the tank 27 and for maintaining a predetera, mined water level in said tank. A supply pipe 31 extends from adjacent the bottom of the tank 27 for. supplying water to a boiler 32 which is likewise disposed adjacent the rear wall 28, beneath and spaced from the tank 27; In the form of the apparatus as disclosed-in Figures 1 to 7, the boiler 32 has a top wall 33 provided with three spaced openings 34. 'I 'hree elongated cup shapedmernbers forming cylinders 35, 36 and 37 have uppererids secured to or formed integral with a plate 38, through which said upper ends of the cylinders open. Said cylinders extend downwardly through the *openings34 and; the plate 38 rests upon the top wall 33 for supporting the cylinders within the boiler 32.. A cover plate 39 having openings 40 registering'with said cylinders may be dis-g posed on the upper side of the plate 38 and secured thereto:

by fastenings 41.

A receptacle 42 is securedagainst an end wall of the boiler 32 and the interior of said receptacle communi-' cates with the interior of the boiler 32 through a lower passage 43 and an upper passage 44. The supply pipe v 31 has an opposite end opening into the lower end of the cylinder 35; A branch 45 oft-he pip.e"3'1 discharges into a downwardly opening valve seat 46'0'f the receptacle 42. A float 47 is mounted for vertical swinging movement within the receptacle 42 and carries a valve 48 for closing the valve 'seat 46 wh'eii'tlieliquid level in said receptacle 42 and-boiler 32 are at a proper height? The branch conduit 45 has a check valve 49 permitting? a flow of liquid theretlirough-towa'rd the 'valve"seat and preventing a flow" intlie oppositedirectiori "I'he'f conduit 31 is provided with a check valve 50 '1o6ate d therein'between the tank 27 andbranch conduit 45." conduit 31 has 'a'bypass conduit'51 extending "around the y der 35.

a An electric motor 53 is supported above and beyond reducer 55, so that said shaft-56'is driven at-a'substantially 'lr'educed speed relative to the motor shaft 57. V The shaft-56 is provided with three cranks58 which are disposed above the cylinders 35-, '3'6 and 37. Pistons 59 are reciprocably'mounted in said cylinders'and are contnected 'by-connecting rods 6Q to the cranks'58 disposed 7 v a l movement'to open positions.

thereabove. p Y- t i I V ,t V and its piston 59 forms a 'p 'ump for maintaining 'a proper liquid-level in the boiler; 32. On each upstroke of the pump piston, water 7 from the tank 27iis' drawn' past' the' check 'valve 50 toward thepnmp cylinder 35: If the-liquid level in thel boil'e'r 32and re ceptacle 42 arelow so that-the valve '48;is*opeh,fand if --'the pump1has been operated sufficiently :126 primed, on' the ddwnstroke of the pump piston, water will be forced jrpwardly through thefbranch, conduit'45past the check'valve 49 andinto the receptacle 42 to'replenish the sup lypr; water'in the boiler 32; The check valve 49 ppens morereadily'than 'ther check valve 52. 'Howven when the float controlled-valve 48 is closed said a valve with the' checkvalve 49 offers a greater resistance than the check valve 52. Accordingly, if no water is needed in the boil'er"32, water from the pump cylinder 2 ss will beforced'Iback toward the tank 21 through the bypass. conduit 51 and past the check valve 52 thereof portion 81 has an inwardly opening check valve 82 at the inlet end thereof through which air is drawn into the conduit 79 and cylinder-37 on the upstroke of the piston 59 of said cylinder. The conduits 76 and 79 have flexible portions 83 permitting the ends thereof, which are connected to the infuser head 70 to move upwardly and downwardly therewit-h in the partition opening 77.

A conveyor apparatus is disposed inuthe cabinet 23 beneath the infuser head 70. Said apparatus, designated generally 84, includes substantially cylindrical housings 85 and 86 constituting endportionsofthetconveying ap paratus. Said housings 85 and 86 have remote sides which are hingedly mounted at 88 for outward swinging Each housing has a reel 89 disposed therein and supported on a shaft 90 for rotation of the reels within the housings. The housings 85 and 86 have upwardly extending passages at the remote ends thereof. The passage 91 of the housing 85. constitutes the outlet thereof, and the passage'92'ofthe housing 86 constitutes the inlet; flhe conveyor structure, includes a rigid plate or'bar'93'extending between the outlet 91 and inlet 92 and which has a' 'aerfcnfatedportion 94 disposed directly'b'eneath the'infuser head 70 A flexible tape 95 iswoundbnrthe reelf89 of thehousing 85 and has an endextending therefrom through the outlet 9 1, along the upper side" ofthefbar 93, thence throughthe inlet 92, and the. opposite endof said' tape is wound on the reel 89'of the housing" Packages 96 are secured to' longitudinally spaced portions on the when the float-valve 48 is closed, to thusmaintain a proper liquidlevel intbe boiler 32 atalltimes.

A wvertical: partition wallf61 is fixedly'mo unted in the upper "part of thefcabinet 23in front of and adjacent the tank-27 and boiler 32.- A supporting bracket'62, as' seen in Figure '3,' is secured mend supported on; the forward sidejof the wall 61 and'provides a support for'an electric motor 63andaspeed reduction unit 64. f Shaft 65 is coupied to the motor shaft 66 by said unit 64' and is drivenat a reduced speed relative ,to the motor shaft 66."

As seen in Figure 2, a housing 114 is secured ;by si1itableibrackets 115 to the inner side of pthe'cabinet front wall 24 and 'is disposed adjacent the top of saidhfront'l wall, ,as seen in Figure 5. The housing 114 constitutes a magazine which is divided intovertical spacesjlldby partition walls 117, as bestseen in Figure-16L Atronei P9; th m saainel mihsflsea s sh: two adi cent spaces 116 two such partition walls 117 are. pro vided and are disposed in spaced apart relation to one another. Each space 116 is adapted to contain a stack of drinking cups 118 of a conventional disposable type. A plurality of shafts 119 and a plurality of shafts 120 are disposed on outer sides of spaced parallel walls 121 and 121a, respectively, of the magazine 114 and each shaft 119 and 120 extends through and is journaled in extensions of two of the partitions 117. Shafts 119, and likewise shafts 120, are disposed in aligned end-to-end relation to one another. Said walls 1'21 and 121:: have openings 122 communicating with each of the cup compartments 116. A spur gear 123 is fixed to each shaft 119 and 120 and extends inwardly through the opening 122 across which said shaft extends. The spur gears of the oppositely disposed shafts 119 and 120 are spaced apart a distance so that said spur gears are disposed in the cup column 116 which said shafts straddle to mesh with the flanges 124 of the two bottommost cups of the cup stack contained in said column.

The shafts 119 and 120 are connected by four trains of gears 125 which are disposed between the walls of each pair of partition walls 117. Each such gear train 125 connects a shaft 119 to the shaft 120, disposed opposite thereto, and includes two intermediate gears 126 which are fixed to or journaled on'shafts 127, which shafts are supported by the walls of said pair of walls 117, and two gears 128 which are fixed to said shafts 119 and 120. The gears 128 extend through openings 129 in the housing walls 121 and 121a and mesh With the intermediate gears 126, which in turn mesh with one another, as clearly illustrated in Figure 18. Thus, when any shaft 119 is rotated the shaft 120, disposed opposite thereto, will be rotated in the opposite direction.

A shaft 130 is journaled in extensions 131 of the partition walls 117 and is spaced outwardly from the shafts 119 and the gears fixed thereto. Four single toothed gears 132 are fixed to the shaft 130 in alignment with the four gears 128 of the shafts 119 and are disposed with the teeth thereof turned at 90 arcs relative to one another.

A bracket 133 is disposed beyond one end of the housing 114 and is preferably supported thereby. A ratchet wheel 134 is fixed to an end of the shaft 130 and is disposed over a part of the bracket 133. A solenoid 135 is fixed to and supported on the bracket 133. A pawl 136 is pivotally mounted on an extension 137 of the armature of the solenoid and is disposed to engage be tween the teeth of the ratchet wheel 134 for turning said ratchet wheel and the shaft 130 clockwise, as seen in Figure 17, when the solenoid 135 is energized, formoving the pawl 136 from left to right toward said solenoid. A holding pawl 138 is pivotallymounted on the bracket 133 and spring urged into engagement between the teeth of ratchet wheel 134 to allow said ratchet wheel to be turned clockwise by the pawl 136 and to prevent the ratchet wheel from turning in the opposite direction on the return stroke of the pawl 136. The pawl 136 is moved in the opposite direction or away from the solenoid 135 and relative to the ratchet wheel 134 by a compression spring 139. A holding pawl 140 is pivotally mounted beneath each gear 123 of the shafts 119 and is spring urged into engagement between the teeth of said gear to allow the gear to turn counterclockwise, as seen in Figure 17, but to prevent clockwise turning'of said gear. Thus, each time that the pawl 136 is displaced toward the solenoid 135 to turn the ratchet wheel 134 a quarter of a revolution in a clockwise direction, one ofthe four single toothed gears 132 will mesh with and turn its associated gear 128 a twelfth of a revolution counterclockwise to thus turn the shaft 119 and the gear 123 thereof counterclockwise a twelfth of a revolution. Similarly, the shaft 120, disposed opposite said shaft 119, and its gear 123 will besimultaneously rotated clockwise a twelfth of a revolution by the gear train 125 which-is 6 associated with said shafts 1 19 and 120. Each time that two opposed. gears 123 arerthus rotated, the adjacent portions of said gears will move downwardly so that flange 124 of the bottommost cup disposed therebetween will be disengaged by the gear teeth and released to drop downwardly by gravity from the column 116. As the gears 1 23 disengage the flange 124 of the bottommost cup, said gears assume positions in meshing engagement with theflanges 124 of the two cups disposed immediately above the cup just previously released. Cups are thus released successively from the four stacks of cups 118, so that the number of cups in each column 116 will be substantially the same at all times.

Figure 19 illustrates a slight modification and Wherein gears 123a are substituted for the gears 123. The gears 123a have their toothed peripheries 141 concavely bowed in cross section to conform to the curvature of the portions of the cup flanges 124 engaged thereby.

As seen in Figure l, the. cabinet front wall 24 has a relatively large opening 142. As seen in Figure 5, a receptacle 143 is secured to the inner side of the front wall 24 and has an open front which registers with the opening 142. A chute 144 has an enlarged open upper end 145 which is disposed directly beneath the open lower ends of the 'four columns .116 for receiving the cups 118 which are released therefrom. The holding pawls are pivotally supported on said upper end of the chute. Said chute 144 tapers downwardly and has a restricted. lower end extending downwardly into the upper portion of the container 143. Said restricted lower'end of'the chute 144 has an opening or notch 146 in the front side thereof and has a restricted opening 147 in the lower end of thechute in which the flange 124 of a cup .118, fed downwardly through said chute, is releasably confined to support the cup. The opening or notch 146 opens downwardly through said bottom opening 147; A funnel member 148 extends downwardly through the top wall 143 of the container 143 and has an angularly extending lower discharge end 150 which extends into the lower portion of the chute 144 and is disposed in apartition 151 and discharges from the lower end of said partition. The partition 151 extends between the front and back walls of the chute 144 and is disposed midway between the tapered side walls thereof, so that the cups 118 can slide: downwardly on either side of the partition to be engaged in the opening 147. With a cup 1 18' thus supported in opening 147," the discharge end 150 of the funnel is positioned to discharge into said cup.

-A rigid conduit 152 has a flared upper inlet end 153 which is disposed against and secured to the underside of the bar 83' around the. perforated portion 94 thereof. The lower discharge end of the conduit 152 is disposed directly above the flared upper end of the funnel 148 when the cabinet frontwall' 24 is in a closed position,

as seen in Figures'S and 6.

The shaft 90. ofthe reel contained in the housing 86 is connected to the shaft 101 by a belt and pulley drive 154, as seen in Figure 3. A drain pipe 155 is supported by and extends downwardly from the bottommost portion of the housing 86. and discharges into the receptacle 156 which is mounted in the cabinet 23, beneath said drain pipe 155. a

A coin box 157, as seen in Figure 5, is mounted on the inner side of the cabinet front wall 24 and a conduit 153 leads from the lower end of said coin boxto a coiri receptacle 159 disposed therebeneath. The wall 24 has a coin slot 160, as seen in Figure l, which opens into the upper part of the box 157.

As seen in Figure 4 and as illustrated diagrammatically in Figure 7, aplurality of electric switches are supported by a bracket member 161 which is connected to and extends from thespeed reducer 55, and the portion of the shaft 56, located between said speed reducer. 55 and the adjacent crank 58; is providedwith'ca'ms foroperating the switches; vOnecontact 162 of 'a coin actuated switch is connectedtoelectric current source .163 by a conductor a wire 164. l- The othercontact "165. of said switch. is 'connectedby. aconductor wire 166 to one post of the motor 53; A ground Wire 167' leads from the other post of 7 the 'motor153.

The chamber 42a, which-:replac'es the: chamber 42,'is spaced' from the the associated.

therewith for turning the shaft 97inone direction, the shaft 97a is-turned counterclockwise for feeding" the tape 95afrom left to right" beneath the 'irifuser head 7021 by a ratchet wheel 194 which is mounted on the shaft- 97aand mesheswith a rack 195. The rack 195'extends slidably through another part of the guide. 190 and constitutes the lower end of a bar 196, and the upper end of said bar 196 forms a second'rack197- which is disposed to be engaged by a gear segment198 which is fixed to the shaft 56a. A collar 199 is fixed to the bar 196, immediately below the rack( E7, to provide an abutment for the upper end of a compression spring 200. The lower end of the spring 2% rests on the guide 190 and urges the racks 19S and 197:to an elevated position as illustrated. A pawl and ratchet 26-1 connects the ratchet wheel 194 to the shaft 97a for turning the shaft 97a, counterclockwise and for permitting the ratchet wheel 194 to turn clokwise relative to said shaft. When the shaft 27a is turned counterclockwise, the tape 9521 is fed from left to right beneath the infuser headfitla in the same manner that the tape 95 is moved.

The shaft 56a in addition to operating the pistons 59a of the three pump cylinders 350,361: and 37a during each revolution thereof, additionally revolves the cam 192a to displace'the infuser head 70a downwardly, and also rotates the gear segment 193a to displace thebar 196 downwardly. The cam 192 first moves the infuser head 70a downwardly so that coffee, can be brewed in the same manner as previously describedwith reference to theapparatus 22. The cam 192 then moves out of engagement with thehead 191 so that the spring 193 can return the infuserhead 70a to an elevated position. Immediately thereafter the gear segment 19$ moves into meshing engagement'with-the rack 197 and thereafter in its downward travel displaces the rack 197 and like wise the rack 195 downwardly.. The rack 125 in travel-I ing downwardly turns the ratchet wheel 194 and shaft 97a counterclockwise. Before the shaft 56:: completes its revolution the-ratchet wheel 198a disengages ther'ack 197 so that the spring 200 can move the racks back to their elevated positions of Figure), during which niove-. ment the ratchet-wheel 194 rotates relative to the shaft 97a. If preferred, the rack 198 and cam 192 can be so disposed on the shaft 56a that the tape 95a will be initially moved to position a fresh filter package 96a beneath the infuser head 7 a before said head is displaced downwardly. The. shaft 56a is driven by'a motor 53a through a reduction gearing 55a. The electric circuit of the, motor 53a may correspond to the electric circuit of the motor 53, as previously described and as illustrated in Figure 7. However, in lieu of the five switches and five cams of the timing unit as shown in Figure 7, the apparatus 22a employs a simplified-timing unit including only. the three switches 170a, 172a-and 173a, and which are actuated by the.cams 180a, 183a and 185a, respectively, Cam 189a closes the switch170a in the same manner andrfor the same purpose that theswitch 170 is closed; by the cam 180. Cam'183a closes the switch 172a in the same manner and for the same purpose that the switch 172fis closed by the cam-183,- andthe cam 185a closes the switch-173a in-the-same manner' and for the samepurpose that the'switch 173'is-closedby'the cam 1 85. The cup holdingand dispensing means of the apparatus 22a corresponds with and-functionsinthe same manner as the cup holding and dispensing meansof the apparatus 22 and accordingly the illustration anddescription thereof isgrnot repcated.

Figure 8 ,and.l 0 10.15. disclose .another..variation of the beverage, maker; and. dispenser, designated generally 7 22b, which. includes a conveyor. apparatus. 84b, corresponding to:.the.apparatus.84. Theinfuserheadlillb is supported by a rod 68b, a spring 193b and a stationary guide 190b, and is displaced downwardly by a cam 192b, in the same manner as the infuser head 70a. The tape 95b carrying the filter package'sp96b is moved from left to right, as seen in Figure 8;beneath theiinfus e'r head'70b by an actuating means corresponding to the actuating means of the apparatus 22;; and including a. double rack bar 1965 which is intermittently displaced downwardly by a gear segment 198 b and which is moved upwardly by a compression spring 20012.

Thelapparatus 22b.1 1tilizes a boiler 32b, corresponding to the boiler 32, and including the parts associated there-J with. The crankshaft 56b operates the cranks associated with the boiler 32b and is driven byan electric motor 53!) through a reduction gearing 55b.

A shaft 203 is disposed parallel to the shaft 56b and is journaled in bearings 204and 205 which are supported by opposite side walls of the cabinet 23b. The cam 1921) and the gear segment 19-8b are fixed to the shaft 203. countershaft 206; is jo-urnaled in the bearing 205 and a bearing '297 and is connected to shaft 56b by meshing bevel gears 203 and to shaft 203 by meshing bevel gears 209.

A shaft 210 is journaledin bearings 211 which are supported 'by one side walleof the cabinet 23!). The en'dof the shaft 20$,disposed remote from the meshing bevel gears 299, is connected to the shaft 210 by a wormgear. 21 2. 'A- disc 213 is fixed to the forward end of the shaft 210 and is provided in its forward face with circumferentiallyspaced sockets 215, as best seen in Figures ll, 12

and14l A hollow shaft 216 is journaled in an opening 217 of the cabinet front wall 24b and has a collar 218 secured thereto and disposed against the inner side of the wall 24b. A disc 219 is fixed-to the inner end of the hollow shaft 216 and is disposed adjacent to and facing the forward sideofthe disc 213. The disc 219 hasa radial recess 220 in its opposite, forward side and an opening 221 opening through the rear side thereof and into the outer end of said recess.

A'rod 222' extends loosely through the hollow shaft 216 and has 'a laterally ofiset end 223 extending through the opening 221 and which is connected to the first mentioned rod portion by a part 224 of said rod which engages in the rece'ssZZG. i

' The outer end of the hollow shaft 216' extends into a hollow kn'ob'225 which ismounted by said hollow shaft on'the iouter' side of the wall 24b. The outer end of the rod 222 i s secured to the outer endof the knob 225 by'a' pin 222a. A collar 226 is secured to the outer end of the hollow shaft 216 and'is disposed within the hollow knob 225; A coinpression spring? 227 is contained within the knob 225l'and has on end bearing against the inner wall 2 28 of said knob and its opposite end bearing against the collar 226, for urging said knob 225 and the rod 222 inwardly. relative to the hollow shaft 216 and disc 219' for projecting 'the "offset rod portion. 223. through the opening .221 andinto engagement with a socket 2156f the; disc. 213'. Saidlrod.portion223forms a finger for coopera-' tionwith. anylone of the'sockets 215 for disengageably couplingfthe. disc 219' and hollowlshaft 216 to the shaft 216.

Theknob wardside of the cabinetfrontrwall; however, normally saidrk'nob and the parts associated therewith will not be utilized in conjunction with a beveragelmaking and dis; pensing. apparatus which isfcoin operated. The 'partfdf the cabinet front wall surrounding the knob 225 forrhsa dial face 229 having a ring of circumferentially spaced numerals 239 arranged counterclockwise andspaced apart a distancere'lative, to one another corresponding to the spacing; between the sockets 215. The knob 225 has a pointer 231for use with said dial face.229.' A normally ,open electric switch 232.is;supported.by. a bracket 2'33jwhich islsecured to, the inner, side of. the wall 24b. Switch 232 is disposed in a position spaced from a part of the periphery of the disc 219 and has a slidably mounted actuator rod 234 extending outwardly 225 isshown in Figure I mounted on thefortherefrom toward the disc 219 and spring urged by a The-roller '237 normally bears against the, periphery of the disc 219 and when so disposed holds the actuator rod 234, displaced inwardly of the switch 232 for maintaining said switch in a circuit closing position. The periphery offthe disc 2:19 is provided with a groove 238 to receive the roller 237 in one position of rotation of saiddisc 219, for permitting the spring to displace the rod 234 outwardlyto open the switch 232. 7

As seen in Figure 10, the shaft 561; carries three cams 7 180b, 183b, and '185b for closing three switches corresponding to the switches 170a, 172a and 173a, respective- 7 1y. Said switches are mounted beneath'the cams on a supporting'bracket 239. The switch 170b, actuated by the cam 18Gb is shown in Figure 15. As seen in this view, thenormally open switch 232 is interposed in an electric circuit 240' of themotor 53b, and the switch 170b'is interposed in a secondary holding circuit 241 of themotor 53b. s

' When the roller 237 is engaging the groove 12 38 and the switch 232 is in an open position, the-pointer 231 is disposed over the 0, between the numerals I and 8' of the dial face 229. The knob 2225 can be turned clockwise forturning the shaft 216 and disc 219 togetheriwith the rod 222, relative to the shaft 210 and disc 213. As seen in Figure 12, the sockets 215 and finger 223 are beveled, as indicated at 242, toallow the finger 223 to be carnmed out of each socket 215 as the disc 219 is turned clockwisejrelative to the disc 213, lacking from left to right of 'Figure 11. 'In this manner the pointer 231 can beset overa selected numeral 230 designating the numbier of cups of coffee to be dispensed in succession without interruption of the operation of the apparatus 22b. When the knob 225 isthu's set the finger 223 will be urged into engagement with a socket 215 by the spring 227.; This turning of the disc 219 will move the groove 238 thereof out of engagementwith the roller 237 to eflect closing 'of the switch 232*to complete the electric circuit 240 for energizing the motor 53b.

The operation of the apparatus 22b in dispensing a plurality of cups of cotfee in succession and without interruption of the operation of the apparatus, will be the same as previously describedin connectionwith the apparatus 22d, except'thatthe switch 17% and the cam 1811b will not be 'eifected to break the electric circuit to the motor- 53b until the disc 219 has been turned with the disc 213, sufliciently to return the groove 238 to a position to 1'6? ceive the roller 237. This will occur as the last cup of coffee is-being" dispensed. At such time the circuit 240 will be broken but the motor 53b will be maintained en-- ergized by the closed circuit 241 until dispensing of the last cup oi-coffee has been completed and the cam 180b; ;permits the :switch 170b to resume an open position to break thecircuit 2 41. Rotation of theshaft 56b drives the shaft 203 which in turndrives the shaft 210 through 1 the worm gear 212. The shaft 210 rotates clockwise, as

viewed from left to right of Figure 11 and makes one.

until the switches 232 and 1701; have both resumed open positions. V e Figure 20illustrates a simplified form of tape conveyor 84c .wherein open' top containers 85c and 860 replace the .7 housings 85. and 86 respectively. The 'tape 95c contain ing the unused filter'packages96c is stored in lapped tape portion on which said packages are'carried are defposited in the open top waste storage box 860.
